No name hinge, turned (barrel) 20×80 mm — door/joint hardware, steel cylinder hinge

Turned (barrel) hinge 20×80 mm is a compact steel cylindrical hinge designed for vertical pivoting of doors, gates and cabinets. Intended for applications where a simple, low-profile bearing point is required, this hinge fits into barrels or mortises in wooden and metal frames. The geometry and steel construction make it suitable for light to moderate loads in residential and light commercial joinery, providing a discreet pivot that does not protrude beyond the door edge when installed.

Advantages

The steel cylinder design offers durability and consistent rotational movement while occupying minimal visible space. Its turned (barrel) form allows for easy embedding into door and frame cutouts, resulting in a neat finish and reduced risk of snagging. Compatibility with both wood and metal frames makes it versatile for a range of fittings, and the 20×80 mm dimensions provide a balance between compact size and adequate load-bearing surface for typical interior doors, cabinets and light gates.

Suitable for

• Interior doors and cabinet doors in residential buildings
• Light commercial joinery such as shop fittings and display cases
• Wooden and metal framed doors where a recessed pivot is preferred
• Gates and panels with restrained weight and frequent opening cycles

Key specifications

• Type: turned (barrel) hinge, cylindrical design
• Material: steel
• Overall dimensions: 20 × 80 mm
• Mounting style: recessed/barrel installation into door and frame
• Motion: vertical pivot for rotation of door leaf
• Suitable frame materials: wood and metal

How to use

Prepare matching mortises or barrels in the door and frame sized to accept the 20×80 mm cylinder. Position the hinge so the pivot aligns with the desired rotation axis and ensure the door sits plumb before final fastening. Secure the hinge in place using appropriate fasteners for the frame material and confirm smooth rotation across the full opening range. Periodic inspection and tightening of fasteners will help maintain alignment and service life.

Usage recommendations

For optimal performance, use this steel barrel hinge on doors and gates within the intended weight range and avoid overloading. Select corrosion-resistant fasteners or surface treatments if installing in humid or exposed environments. Regularly check alignment and fastener tightness, and apply light lubricant to the pivot if movement becomes stiff.
